Bakit ma-traffic sa Ortigas Avenue? [Why is Ortigas Avenue congested?]
Bakit ma-traffic sa _______? I usually pose this question to my audience (e.g., students, trainees, etc.). In this post, I attempt to answer the question in the title using data we collected for Antipolo City’s Sustainable Urban Mobility Plan (SUMP). In one of the workshops, I asked the participants from the local government unit (i.e., from the various transport-related offices of Antipolo City) to try to determine the traffic mix for Ortigas Avenue Extension (also named Corazon Aquino Avenue from the Antipolo side) based on the traffic counts conducted at a station along the section that connected Antipolo with Taytay (at Tikling Junction). They also had performed vehicle occupancy counts along the same location so
These are just the numbers from the Antipolo surveys. Note that Ortigas Avenue Extension serves as a collector for the Rizal towns including Taytay and Cainta as well as for Pasig City. If we have similar numbers for the traffic mix and occupancies, then we can conclude that most people are actually using private vehicles with a surprising share being carried by motorcycles! That seems to go against the narrative that private vehicle ownership is low and that most people take public transportation. At least for the case presented here, that is not true, and we seem to be underestimating private vehicle use or preference.

On transport strikes – are they still relevant or effective?
One of my students casually asked me about the effectiveness of transport strikes. I replied that while the strikes may and can raise awareness of the issues being protested, their effectiveness may have been diminished as people have become insensitive not just to them but to many of the issues we face these days. The latter includes the political mess we have that affects everyone regardless of who you side with.
Here is the series I wrote back in March 2023 – “A Brief History of Transport Strikes”:

Traffic congestion due to flood control project – another interceptor for Cainta and Marikina
This week, another flood control project commenced that is expected to bring more congestion along Marcos Highway. The construction involves constriction along the corridor. That is, the capacity of Marcos Highway will be reduced due to the space required by the project. This meant the closure of U-turn slots and the reopening of the Marcos Highway-Felix Avenue-Gil Fernando Avenue intersection. There is significant traffic from Felix that turns left to Marcos Highway towards Quezon City. Instead of continuous, uninterrupted flow towards the former U-turn slot across Burger King, vehicles now need to queue for their turn to make a left turn. And this has led to long queues along Feliz Avenue that reaches Karangalan Village, even Vista Verde on a bad day.
Two lanes have been closed to give way to excavations and the installation of large pipes that will connect with the existing drainage in the area. This interceptor will eventually drain to the Marikina River and is expected to reduce flooding particularly in Cainta and Antipolo where residential subdivisions have endured floods during the wet season for many years.
The project will run for a year. That, of course, assumes that there will be no delays for whatever reasons might come up. The LGUs concerned including Antipolo, Cainta, Marikina and Pasig are cooperating with the MMDA to address traffic management issues.

Diskarte sa tag ulan – child rider safety
Sharing this photo of a child taking cover from the rain using her adult companion’s jacket. it is obviously not a safe situation or set up but perhaps it suffices for the moment.
Kids should have the necessary gear like a child- sized helmet for safe riding and a jacket or coat to protect the kid from the rains. The provision of these is the responsibility of adults particularly the parents or guardians of the child.

The latest issue of the Philippine Transportation Journal is out. Volume 8, Number 1 includes five (5) papers derived from the Transportation Science Society’s 2025 conference held in December 2025. PTJ didn’t have a 2025 issue as last year was an EASTS Conference year and TSSP held its 31st Annual Conference in December instead of the usual September or October. Most if not all papers published in PTJ are from the best of the conference including the best paper and best presentation. Authors are given the chance to further refine their papers based on the feedback or comments in the conference sessions, which may be different from the comments received during the review process.
I reproduce below the list of papers in the latest PTJ issue. Three papers are associated with UP Diliman: #2 with the National College of Public Administration and Governance, #3 with the Asian Institute of Tourism, and #4 with the College of Engineering. One paper, #1 is from the University of Asia and the Pacific. The last but not the least, #5, is from UP Los Banos.

On preaching on public transport
I’m sharing this interesting article about a preacher who was asked to stop by commuters in a train in Sydney, Australia:
Why an Entire Sydney Train Turned Against an American Preacher
I suddenly remember similar instances when I was in high school and then as a university student. Some of the buses I rode on my commutes were boarded by preachers. I recall that people just didn’t mind them especially when they finished preaching and started asking for donations. I don’t remember anyone shouting or calling out the preacher to stop. Everyone was just silent and not minding the talk though I’m sure there were those who felt uncomfortable with the situation. Perhaps it’s just Filipinos being kind despite what may be regarded as an intrusion or disturbance. Fast forward to the present and there was a recent incident on a train where passengers made it clear they didn’t want to be evangelized in that way. That’s a complete reversal from my college days in the early 1990s. What do you think? Is a public transport vehicle such as a bus or train an appropriate venue for preaching? Or was/is there a violation of personal space here?

Nice day for a walk!
The sun’s finally out after so many days of heavy rains (and floods). It’s nice to be walking again outdoors instead of indoors (building stairs and corridors, and malls).
It’s quite pleasant out with a cool breeze that encourages us to do outdoor activities. I did my walking this morning and will be walking again later today!

U-turn due to inclement weather
I was on my way to the office this morning to check on our buildings and get some lecture materials. I had to go back as the intense rains immediately flooded the roads along the way.
Here are some photos this morning on my way to UP and when we turned back:
Malacanang has again suspended F2F classes and government offices have been advised to be alternative modes of operations. Is this the new normal when we have inclement weather? Are we supposed to be adjusting again and expected to be resilient in these times?

Commuting through floods
Yesterday’s rains were catastrophic. Reports stated that a week’s rains fell over a period of 2 to 5 hours, depending on where you were in the Mega Manila area. The resulting floods provided misery to people in flood-prone areas as well as those who had to go through the floods on their commutes to their homes. Here are photos from my commute going home yesterday. I relied on Waze for the shortest travel time and the app took me to flooded areas in Cainta. Perhaps it assumed my vehicle can safety navigate the floodwaters?
Flooded street in Gruar Subdivision in Cainta, Rizal
Flooded A. Bonifacio Avenue in Cainta, Rizal towards Taytay, Rizal. This is the main avenue through the heart of Cainta.
Flooded streets in the area leading to Hunters ROTC Street. These residential areas are prone to flooding and children commonly play in the floodwaters – certainly at risk from getting sick from whatever it is in the waters.
This is Ortigas Avenue Extension and on the way up to Antipolo. This area wasn’t flooded before and residents attribute the floods to the high-rise residential buildings and commercial development in the area. That’s actually a lot of run-off not absorbed by a drainage system that’s supposed to have been constructed with the developments. Did the local government of Taytay, Rizal make an evaluation of this before approving the projects?
Is there an end to this flood problem? Are the solutions really being implemented or, as we’ve learned the past so many months, are we being taken for a ride by our so-called leaders and agencies that are supposed to address these problems. People are supposed to be tired of the resilience story being peddled by politicians but the clamor seems to be in social media only and the real people who are lobbying for solutions have to contend with trolls who are also peddling their own narrative for their masters.
